<a name="gstreamer-plugins-tee.description"></a><h2>Description</h2>
<p>Split data to multiple pads. Branching the data flow is useful when e.g.
capturing a video where the video is shown on the screen and also encoded and
written to a file. Another example is playing music and hooking up a
visualisation module.</p>
<p>One needs to use separate queue elements (or a multiqueue) in each branch to
provide separate threads for each branch. Otherwise a blocked dataflow in one
branch would stall the other branches.</p>
